To remove the shift cable, start by detaching the cable from the negative terminal of the battery and applying the parking brake. Then, block the rear wheels and shift the transmission into Neutral. If applicable, remove the transfer case shield and pry the cable end from the transmission control lever stud. Remove the cable from the transmission oil pan clip and the horseshoe retainer from the shift cable housing. Squeeze the cable retainer and pull the cable toward the back of the vehicle to disconnect it. For vehicles with a column shift, remove the steering column trim filler panel, and for floor shift vehicles, pry the shift cable from the shift lever. Remove the horseshoe clip retaining the cable to the bracket on the steering column and squeeze the cable retainer to remove the cable from the bracket. If necessary, remove the floor console, cowl trim panel, door sill trim plate, seat, and front carpet, and pry the cable grommet from the floor before removing the cable and grommet from the vehicle. To install the cable, follow the reverse order of removal, being careful not to damage the rubber boot. For adjustment, apply the parking brake and remove the retaining clip from the rear support bracket. Separate the body-core adjuster from the range selector pin and place the transmission shift selector shaft and lever in Neutral. Remove the horseshoe retainer from the shift cable and the cable from the transmission oil pan clip. Reinstall the cable onto the transmission oil pan clip and the horseshoe retainer onto the shift cable. Ensure the transmission shift lever and selector shaft are still in Neutral and snap the body-core adjustment onto the transmission selector shaft. Push the locking tab into the body core until it snaps, and insert the horseshoe retainer into the shift cable. Finally, check the adjustment to ensure the shift lever goes into all positions and the engine starts only in the P or N positions. Readjust the shift cable and park/neutral switch if necessary to meet these criteria.

To remove the shift cable, start by disconnecting the negative cable from the battery. Locate the vacuum actuator, which can be found on top or underneath the right fender well. If it is located below the battery, remove the battery first. Squeeze the two locking fingers of the cable ferrule and pull the cable out of the bracket. Remove the cable housing bolts and pull out the housing slightly. Unscrew the coupling nut to detach the cable from the shift cable housing. Remove the shift cable assembly. To install the new cable, guide the end through the hole in the shift cable housing and push it into the shift fork shaft. Install the shift cable housing on the differential carrier and tighten the bolts. Spread the retainer clip, engage the cable end with the actuator, and release the retainer clip. Connect the shift cable to the actuator and attach the vacuum hose to the actuator. To remove the vacuum actuator, detach the vacuum hose and disconnect the shift cable. Remove the actuator retaining bolts and remove the actuator. Installation is the reverse of removal.
